Once again, first determine the
genotypes of the parents. We know that the female is
heterozygous for the rate of head bobbing but
homozygous recessive for the color of her throat
patch. So, what must her genotype be?

Now that you have the genotypes of the
parents, perform a punnett square to determine
what the F1 offspring would be
(remember to place the gametes of one parent
across the top and the gametes of the other parent down the left side. It
does not matter which parent's gametes are placed across the top and which
are placed down the side.):

Your punnett square should look similar to
the one below. If it does not, review the material on
gamete formation and how to set up the punnett
square and try again.
